The Asus ZenFone line was launched way back in 2014 by Asus, a company that originally made a name as a manufacturer of computer hardware. While the Taiwanese electronics giant launched the first 4 main variants of the ZenFone that year, it was in 2015 when the ZenFone name really shone. It was the year Asus launched the highly regarded ZenFone 2. Now, with the current lineup’s top-notch specs and attractive price points, the ZenFone continues to be one of the most regarded Android smartphone series in the world.
